Does your SO ever make up feel stupid when you are upset about something he/she did, and it starts a huge fight?

He has tried it but I point it out and things become civil. He at least apologizes for comments like that and we can move to having a "constuructive " arguement. I am guilty of the same and always apologize for it too. We try to discuss our problems

No, though he may have tried to a few times. I'm very secure with my intelligence, so any nonsense he comes up with when he's mad won't make me feel stupid. I think he generally agrees that I'm smart, so he leaves that out of play when we do argue. If anything, he sometimes makes fun of my lack of common sense, but not in mid-argument.

Being a smart ass just comes so natural to me. My wife says I do it all the time but I honestly do not mean to. Most of the time it's just the way I say things. Not really trying to hurt her feelings or make her feel stupid.

Yea because we see things two different ways or I don't realize he did it for a totally different reason than I would have assumed or he brings in examples of when I did the same and I can't even remember when he does something to annoy me

Sometimes, it's hard to find out if I'm to blame or if it's her... She's older, too. I actually was talking to her about it yesterday, it does not appear that she knows she is doing it but understands. We made up and it was fine, and it sounds like she's trying really hard not to hurt my feelings.
